GUSTAV STICKLEY, OF NE? YORK, N. Y.

OPEN FIREPLACE.

Application filed March 15, 1912.

T 0 all whom it may concern Be it known that I, GUSTAV S'rIcnLEY, of New York city, in the county of New York, in the State of New York, have invented new and useful Improvements in Open Fireplaces, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in open fire places for dwellings and other buildings and refers more particularly to means for heating and circulating currents of air and distributing the heated air to one or more local or remote parts of the building in which the fire place is located.

The main object is to cause the heated products of combustion and air to travel across relative large areas of comparatively thin radiating surfaces within a hollow wall so as to form a receiving chamber from which the heated air may be distributed to any part or parts of the building.

Another object is to conceal the entire radiating medium within the hollow wall or chimney in which the fire place is built, thereby permitting such fire place to be constructed and operated in the usual manner without reducing its efficiency in heating the room in which it is located or exposing any part of the radiator.

In other words I have sought to produce a radiator of the class described which may be easily and quickly incorporated in any style of fire place without detracting from the general characteristics of such fire places.

Other objects and uses relating to specific parts of the fire place will be brought out in the following descriptionzln the drawings Figure 1 is a perspective view of a fire place embodying the various features of my invention, a portion thereof being broken away to show the concealed parts of the apparatus. F ig. 2 is a perspective view of the detached sheet metal radiator box form- .ing a concealed part of the fire place. Fig. 3 is a perspective view of a portion of the fire place seen in Fig. 1 showing the same in transverse vertical section. Fig. 4 is a horizontal sectional view through the hollow supporting wall for the fire place showing particularly the ash pit and cold air flue therein. Figs. 5 and 6 are similar horizontal sectional views through the fire place taken respectively on lines 55 and 66, Fig. 1 showing particularly in Fig. 5 the relation of the radiator to the air chambers at the sides,

the plane of the floor -a and also extending rearwardly some distance beyond the front wall for allowing the fuel to be placed back of the front face of the fire place and establishing direct communication with a superposed fire or draft passage presently described.

The hollow wall l forming the fire alace and its su oortin wall or foundation -2 are preferably the same width somewhat greater than the width of the fuel opening -3 so as to extend equi-distant to opposite sides thereof, the foundation -2 being also hollow to form an ash pit 4 while the sides of the hollow wall or fire place 1 are also hollow forming air chambers 5-- communicating with the interior or main chamber -6.

The chambers 5 and -6- preferably extend from floor to floor and constitute what may be termed air receiving and distributing chambers. That is, the cold air may be taken from the outside atmosphere through an inlet 7 into the base of the air chamber 6 or may be taken from the room near the lower floor line through grilled openings 8- in the side chambers 5 as shown more clearly in Figs. 1, 2 and 5, while the heated air in the upper part of the chamber --6 may be delivered into the adjacent room through a grilled opening 9- inthe rear side of the wall 1 or other suitable conduits 10 in the superposed floor 8 through which the heated air may be conveyed to the next superposed room or to other portions of the buildings as may be desired.

When wood fuel is used, the upper end of the ash pit 4 may be closed by a suitable plate 11 adapted to be supported in any desired manner hereinafter described for receiving and supporting suitable andirons (not shown) but when coal fuel is employed, I preferably provide a grate 12-- which is supported upon a frame work presently described, such frame work being also adapted to support a grill front *l".

The grate -l2- is supported within and upon a rectangular frame --14: which in turn is supported at its ends in a horizontal posit-ion upon ledges 15 on the side walls of the fuel opening -3- some distance above the plane of the floor -a-, thereby leaving an intervening draft passage between the front side of the frame and floor, said passage being closed by a removable shield or plate l6- to prevent the exit of dust into the room and also to cover the ends of the grate bars.

The grate preferably comprises a series of rotary grate bars journaled in suitable bear ings in the front and rear sides of the frame 14, it being understood that the front ends of the grate bars extend forwardly slightly beyond the front side of the frame lflfor the reception of a suitable shaker when the shield plate 16 is removed from its operative position.

The grilled front 13 of the fire box is removably supported in the front side of the frame 1l-., in an upright position thus iermitting it to be removed by simply lifting it upwardly from said frame. In like manner the entire frame 1atmay be easily removed by simply lifting it from its supporting ledges 15- thereby permitting the fire place to be easily and quickly changed for burning wood or coal fuel.

.51 7'1 beating (Moira-I have now described the general construct-ion of the fire place excl usive of the air heating device or radiator which is preferably incorporated in the hollow wall during progressive building and consists of an upright sheet metal box or casing 17 supported centrally within the air chamber 6 with the major portion thereof spaced apart from the front, rear and side walls of the hollow wall -l so as to leave a clear open space around practically the entire surface area of the box and extending from the base of the fuel epening3to a plane some distance above the upper side of said opening and from side to side thereof for the purpose of affording a relatively large heating and radiating area. As shown in the drawings this b x is preferably made of sheet metal and comprises upright front and rear walls 18 and 19-, intermediate upright partitions 20- and 2l, opposite end walls -22 and 22- and top walls -Q3-and 23 all of which parts are united to form a unitary structure with air and gas tight joints. he lower edge of the frontwall 18 terminates a distance above the bottom of the box corresponding to the height of the fuel opening 3 to form a corresponding fuel opening in the front of the box and is preferably deflected forwardly against the inner face of the front side of the hollow wall 1 just above the fuel opening 3 so as to form an air and gas tight oint therewith, the remaining portions of the box front l8- being substantially flat and spaced apart from the inner face of the front side of the wall 1 so as to form additional air space communicating with the air chamber 6.

The lower edge of the rear side 19 of the radiator box is provided with a lateral offset 39 resting upon the upper edge of the foundation wall 2- at the rear of the ash pit 4 and serves to support practically the entire weight of said radiator box, the connection between the front wall of said box and adjacent side of the hollow wall 1- serving to additionally support the box in its operative position. The lower portions of the sides -22 and 22 extend forwardly some distance beyond the upper portions above the ledge as 18 and are closely fitted against the side walls of the fuel opening 3-. to form air and gas tight joints therewith and to addition ally support the radiator box against lateral movement. The upright partition -20 consists of a flat sheet metal plate rigidly secured at its ends to the corresponding ends of the box between the front and rear sides 18 and 19- and apart therefrom, said partition extending from the plane of the base of the fuel opening 3- to a plane some distance above the upper side thereof and in proximity to but spaced apart from the top Wall -23, thereby dividing the interior of the box into front and rear combustion chambers or fire passages .24. and 25 communicating with each other above the upper edge of the partition 20, the front chamber being in direct communication with the fuel opening 3 while the rear chamber 25- extends downwardly from the upper edge of the partition 20 to the bottom of the box and therefore across the entire area and at the back of the fuel opening. It will also be seen that the cold air which enters the chamber -6- through either of the inlet openings 7 or 8 also comes in contact with all portions of the front, back top and ends of the radiator box and also with all portions of the partition plates 26 and 26-, thereby absorbing the heat radiated by said box and delivering it into the chamber 6 from which it may be distributed to adjacent rooms or other parts of the building in the manner previously described.

In order that the heat radiated by the sides of thehollow partition 21-- may be most efficient in heating the air in contact therewith, the upper side of the. space between the partition plates 26- and 26- is left open while the greater portions of the ends of such space are closed by the end walls -22- and -22, leaving relatively small air inlet openings -32- in said ends communicating with the lower portion of the chamber 27- in the hollow partition 21 so as to cause the cold air to travel as nearly as possible across the entire areas of said plates. It will also be observed that the air which may enter the space between the front 18 of the box and adjacent side of the hollow wall 1 will also be heated and delivered into the distributing chamber 6.

The smoke fiue or chimney 30 may be located in any convenient position but is preferably incorporated in one corner of the hollow wall l and rests upon suitable girders -33 and 3 l, the girders -33- being supported in the front and rear sides of one end of the hollow wall -1 just above the plane of the upper side of the fuel opening -3- or rather below the plane of the smoke outlet 29 in the radiator box 17 so that when the smoke flue 30- is built up from the girders -33-, a suitable opening is left therein for registration with the smoke outlet 29-. The girder 3 l is also supported in the front and rear sides of the adjacent end of the hollow wall 1 just over the corresponding end of the radiator box, thus affording additional support for the chimney which may be extended to any height through the roof of the building or may be connected to any other smoke flue if desired.

The front face of the partition 20 immediately back of the fuel opening 3 is -covered with a facing -40- of brick, tile or other heat resisting material extending from the base some distance above the.

upper side of said fuel opening to not only conceal this portion of the radiator box from view but also to protect the partition against burning out at its junction with the fire box or grate, said facing being supported upon a forwardly projecting ledge --39 on the lower edge of the partition and extends from side to side of the fuel opening so as to form air and gas tight joints therewith.
